car overheating

The temperature in my car has been rising beyond the normal limits....it is about 5 degrees from hitting the red zone....I checked the codes and there were none...i checked the fans and they are working....checked the radiator fluid and it is ok....should I change the thermostat? If so how do I do it??? what else could be causing this problem???

Blue coupe, very informative post. Kind of looks like a C++ program I wrote last semester for class. Silver97 you shouldn't have to change the thermostat, unless you suspect it is faulty. There is something that is not allowing the cooling system to do it's job right.

Silver97...before you do unnessary things..try this first...see if there is any air in the system...you can let the air out of a bleed screw on the water pump...that may very well be your problem...air not bled out of the system can cause overheating...

Also check to see if you have a 50/50 mixture...too much antifreeze can cause overheating also...

When you inspect the radiator make sure you are looking at the radiator and not the A/C cooler. The A/C sits in front of the radiator and many times all kinds of stuff will get between the two and will block air from getting to the radiator.
